THE FISHES OF SAMOA. 371 



Samoan specimens are young, and all have the black stripes, but we have no doubt that they are spe- 

 cifically identical with the unstriped Tetraodon immaculatus. The best distinctive character of this 

 species is the black edge to the caudal. 



Color in life of a specimen from Apia, olive, white below, striped ali over back and sides of belly 

 with dark olive; fins pale gray, the caudal edged all around with black. 



1305. Tetraodon lacrymatus Ouvier. Hawaii; Raiatea (Seale). 

 Tetraodon lacrymatus Cuvier. in Quoy & Gaimard, Voy. Uranie, Fishes, 201. 1824, Maui. 

 Oroides latifrons Jenkins, Bull. I'. S. Fish Comm., xix, 1899, (1901), 398, fig. 10, Honolulu. 

 Tetraodon meleagris, Smith & Swain, Proc. U. S. Nat. Mus., v, 1S82, 141, Johnston I.; not of Lacepede. 



This species, which is probably different from Tetraodon meleagris of the East Indies, is known 

 from the Hawaiian Islands. The specimens from Johnston Island, called Tetraodon meleagris, probably 

 belong here, as well as the type of Tetraodon latifrons. Tetraodon meleagris i-^ found in the seas of 

 tropical Japan and China. The single specimen examined by us from the Kin Kiu Islands is 

 apparently different from those called Tetraodon latifrons. The species called latifrons must be the 

 same as the lacrymatus, described long before, from the same waters. 



1306. Tetraodon ophryas Cope. Samoa; Tahiti; Mangareva (Seale). 



Tetraodon ophryas Cope, Trans. Am. Phil. Soc. 1S70, 479, Samoa. 



'Trlraodon setasus Rosa Smith, Bull. Cal. Ac. Sci., II, 6, 18815, west coast of Mexico. 



Oroides ophryas, Fowler, Proc. Ac. Nat. Sci. Phila. 1900, 528, pi. xx, fig. 2; after Cope's type. 



This species is known only from the original type from Samoa. It may be identical with Tetra- 

 odon setosus of the Mexican coast. Tetraodon meleagris Lacepede, from Asia, figured by Jordan & 

 Fowler (Proc. U. S. Nat. Mus., xxiv, 253, fig. 8), also is allied to it. 



1307. Tetraodon g-iganteus Castelnau. New Caledonia. 



Tetraodon giganteus Castelnau, Proc. Zool. Soc. Victoria. 1873, 121, New Caledonia. 



CANTHIGASTER Swainson. 



(Psilonotus Swainson; Tropidichthys Bleeker; Anosrnius Peteis; Eurnycterias Jenkins.) 



This genus consists of small globe-fishes with the back angulated and the nostrils obsolete or little 

 deyeloped. The earliest name, Canthigaster, is defined without mention of any species, but the con- 

 text admits of no doubt as to the species intended. The slightly better development of the nostrils 

 in Eurnycterias Jenkins is a character of very light weight, and the genus Eurnycterias can not be 

 maintained. 



1308. Canting-aster solandri (Richardson). Sue mi mi. Tahiti; Samoa; Guam; Raiatea (Seale). 

 Tetraodon solandri Richardson, Voy. Sulphur, Fish, 125, pi. 57, fig. 4-6, 1845, Tahiti. Richardson, Voy. Samarang, 



19, 1848, Tahiti. 

 Tropidichthys papua, Seale, Bishop Museum 1901. 118, Guam; probably not of Bleeker. 

 ? Tetraodon papua Bleeker, Journ. Ind. Arch., II, 038, New Guinea. 



This little species from Tahiti was originally described as having the body covered with greenish 

 yellow spots, each with a dark border with blue cross streaks between the eyes, with some of the 

 stripes on the back extended as streaks; caudal with blue spots, forming interrupted blue streaks. 

 As one of our Samoan species agrees perfectly with this description, we identify it as Canthigaster 

 solandri. The fish called solandri by Steindachner from Laysan seems to be Canthigaster jactator. 

 The specimens from Guam, called Tropidichthys papua, evidently belong here. Canthigaster papua 

 Bleeker, from New Guinea, is evidently closely related, but it has the blue streaks on the back more 

 or less confluent into lines. 



In our eight typical examples of Canthigaster solandri, from Apia, the spots are small on the cheek 

 and snout and distinctly blue in color. In eight examples from Pago Pago, the spots on the body are 

 duller, and those on the chin, throat, and cheek, as far back as the gill-opening, are dark bronze-blue, 

 eye with radiating streaks, caudal distinctly barred. This may be a distinct species, but it seems to 

 intergrade perfectly with the typical form, one specimen of the latter having larger bronze-blue spots 

 at the throat. We have about 25 specimens from Apia and Pago Pago. 



Life colors of two specimens from Apia, dark brown, orange on side, yellow below, with a median 

 blue, orange-edged streak before vent; sides with round sky-blue spots, most distinct on head; caudal 

 orange, barred with blue spots; dorsal, anal, and pectoral clear translucent; a black spot at base of 

 dorsal.
